In dry climate of Timor island, Se'i is a traditional method employed in order to preserve meat, as a food reserve and security, and also to increase nutritional and economic value of the meats. In the past, the food was actually made from Timorese deer (Cervus timorensis), however, since Timorese deer has been hunted near to extinction in Timor island and thus became rare, domesticated animals such as beef and pork became the main ingredients of Se'i.

Numbers of restaurants serving se'i also has appeared outside of East Nusa Tenggara, such as in Jakarta and Bali.
